SEWING-MACHINE.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application lad August 1l, 189B. Serial No. 688,393.

To all whom it may concern,.-

Be it known that l, JASPER VANNETTE, a citizen of the United States, residing at Tifn, in the county of Seneca, State of Ohio, have invented certain new and useful Improvements in Sewing-Machines, of which the following description, taken in connection with the drawings herewith accompanyin is a specification.

his invention relates to sewing-machines, and more particularly to lock-stitch sewingmachines of that class in which both the ulpper and under thread are taken direct from t e ordinary commercial s ool of sewing-thread, the advantages oere by such class of inachines being that a greater su ply of under thread is rovided than that a orded by the ordinary obbin, whereby the machine may be run longer without stopping for a new thread-supply and also the trouble and loss of time attendant upon winding the bobbin is avoided.

M invention has for its object to im rove mac lnes of the class referred to by ren ering the same capable of being operated' at a greatly-increased speed, reducing noise and vibration, and otherwise rendering the same more effective and desirable than heretofore constructed.

In the accompanying drawings, in which I have illustrated only so much of a sewingmachine as is necessary to explain my invention, Figure 1 is a bottom view of a portion of the bed-plate of a sewing-machine with certain parts of a stitch-forming mechanism thereon embodying my invention. Fig. 2 is a longitudinal section through line 2 2 of the construction shown in Fig. 1. Fig. 3 is a detail view of certain oi the parts shown in Fig. 2, showing the change in position of the same at a different time during the formation of a stitch. Fig. 4 is a front end view of the machine with certain of the parts removed and in section to more clearly show the reciprocally-moving spool-supporting frame, spooldriver, and loop-pusher and the connection between such parts. Fig. 5 is a detail view, partly in section, showin thc relative positions assumed by the spoo -supporting frame, spool, loop-s ireader, and loo -seizing hook at a time w en the latter rst enters the thread-loop thrown out by the needle, the several parts being shown in elevation. Fig. 6 is a v1ew similar to that of Fig. 5, showing the position assumed by the parts at a different time during the formation of a stitch,

and broken away, also showin different ositions assumed by the parts uring the 01'- maticn of a stitch. Figs. 9 to 13, inclusive,

are views illustrating the operation of certain of the moving arts 1n taking the thread-loop from the nee e and ass'ing it around the spool carrying the undjer thread, whereby it will interlock with the latter. Fig. 14 1s a view of a spool-case embodying my invention. Figs. 15 and 16 are views illustrating modifications in the construction of certain of the parts to be hereinafter referred to, and Fig. 17 is a perspective view of the loo -seizing hook detached from its operating-shaft.

To explain in detail, c denotes the bedplate of a sewing-machine, and a the needle. have not considered it necessary toillustrate any of the stitch-forming mechanism above the bed-plate other than the needle, as it Inav be of any well-known kind.

eneath the bed-plate a is a spool-supporting frame l), which is adapted to be su ported in any suitable manner to be capab e of having a reciprocating movement, the same, as more clearly shown in Fig. 1, being provided with arms or extensions b', which are loosely seated within openings formed in hangers a? c2 on the under side ol' the bedplate. This frame which may be of any suitable form, is provided with two pins or rods b2 b2, arranged in line with each other, on which an ordinary commercial spool b3, carrying the under-thread supply, is adapted to be loosely supported to have a reci )rocating movement. A space or opening lv* is provided between the adjacent ends of the two pins b2 b2, through which the needle-thread oop is passed by suitable means Jfor the purpose of receiving the reciprocating spool 3 therethrough. After the spool has been assed through the needle-thread loop the atter is then drawn back through the opening between the pins by the ordinary take-up acting above the cloth-plate of the machine and caused to interlock with the under thread and form a lock-stitch in the usual manner. The spool o, which is preferably inclosed in a cylindrical case h, is reciprocated back and forth from one to the other of the rods b2 by means of a driver c. This driver, as herein shown, consists of a frame or plate c", which is supported to slide in guideways c2 c2 in the spool-frame b, as more ICO clearly shown in Figs. 2 and 4, and provided with suitable arms ca e4 for loosely engaging with the o posite ends of the spool. A rotating sha t d, supported in suitable bearings on the under side of the bed-plate, is provided with a crank d, which is connected, through the medium of a itn1and2,with a fixed pin c5 on the spool river c, so as to communicate the desired movement to the latter. It will be understood that when one end of the spool b3 has entered into the needle-thread loop which has been passed through the openings b4 between the ends of the rods b2 such needle-thread loop cannot be drawn up by the take-up to complete the stitch until it has passed ofi1 the opposite end of the spool and is enabled to pass through the said openin b4 between the ends of the rods b2. Therefgore as an important feature of my present invention I have arranged for reciprocating the spool-frame in opposition to the movement of the spool and its case, whereby the said opening bt of the spool-frame after receiving the needle-thread loop therethrough for the purpose of being passed around the front end of the spool will be moved toward the opposite end of the spool during the movement of the latter in the contrary direction, and thus enable the threadloop to be drawn off the spool and through the said opening b4 in one-half the time that would be re uired. in case of the individual movement oV the spool alone. The spoolframe l) receives its reciprocating movement also from the rotating shaft d through the medium of a second crank d3, with. which the latter is provided, and a pitman d, connecting said crank with a pin b6 on the spoolframe, as more clearly shown in Figs. 1 and 4. The movements of the spool-driver and the spool-frame in opposition to each other, as described, is secured by so arranging the two cranks d and d3 that the throw o1 one is opposite to the throw of the other. By reason of such movement of both the spoolframe and s ooldriver in opposition to each other the tlllurow of movement of such parts for the purpose of passin the needle-thread loo around the under t ead is only onehal of that which would be required in case the movement was confined to one of the parts. I am thus enabled to employ easy crank or eccentric movements to operate the said parts, and so materially diminish noise, vibration, and friction, as well as increase the durability and general effectiveness of the machine.

The body portion of the spool-frame b, within which the spool-driver is sup orted to slide, is rovided with a central e ongated o enin 7 therein, through which the cranksffaft extends, as more clearly shown in Fig. 2, whereby a direct line of draft is secured between the cranks d and d and the pitman connected spooldriver and spoolframe. The said cranks being located at that side of thc spool-frame b opposite the spool also prevents possibility of the ends of tie thread from either the upper or lower spool coming in contact with the same and getting entangled therewith.

The means for takin r the thread -loop thrown out by the nee le and passing the same around one end of the spool b3 consists of a loop-seizing hook e, which first enters the needle-thread loo and opens the same, and a loop-spreading ingerf, which engages with one side of the opened loop and then, acting in combination with the hook c, spreads the loop through the opening b4 of the spoolframe and around the end of the spool. The hook e, which is carried at the front end of a rotating shaft e', mounted in suitable bearings on the under side of the bed-plate, is formed with an attaching-shank e2, having a substantially triangular shaped loop-seizm blade e3 at one side thereof, which is pointe at its front end and tapered to considerable Width at its rear end. This form of blade insures the ready entry of the same into the needle-thread loop and after receiving a partial turn, as shown in Fig. 6, opens the loop to considerable width and causes the same to assume a well-defined triangular shape with the forward or upper side thereof in the path of the loop-spreader f, which latter moves forward at such time in a path at right angles to the path of the loop-seizing hook and engages with the said upper side of the loop, as shown in Figs. 2 an 11, and carries the same over and across one end of the spool and through the opening b4 of the spool-frame. This loop-spreader moves in a substantially circular path around the spool-case, and as it engages one side of the loop and carries it over and across the end of the spool the hook e, with its engaging ortion of the loop, continues its downwar movement in a path parallel with one side of the spool, and so acts in combination with the loo -spreader to pass the loop around the en of the spool, whereby the latter may be passed through the same.

The detailed operation of the parts in taking the needle-thread loop from the needle and passing it around the spool, as illustrated in the drawings, is as follows: The loog-seizing blade first enters the needle-threa loop thrown out by the needle, as shown in Figs. 5 and 9, and after fully entering the same causes the thread-loo to receive a partial turn as oneside thereof passes around to the rear end of the blade, as in Fig. 10, whereby the sides of the loop Will be operated apart in a direction at right angles to the path of the loop-spreader. Continuing its movement, the loop-seizin blade causes the loop to assume a trianguar shape with the sides Widely separated and the upper side in the path of the loop-spreader, which now advances to IOO IIO

engage the same, as in Fi 6. The sidesiof the loop bein thus Wide y separated permits the use o a long thread-engaging finger f on the loop-spreader, which may engage with one side of the loop Without liability of striking the other and extend a considerable distance over the end of the spool to insure the thread being carried thereover. After the parts have reached the position shown in Fig. 6 the loop-spreader continues to move forward and the loop -seizing hook down- Ward, as shown in Fig. 11, until they reach the position shown in Fig. 7, at Which time the spreader has carried one side of the loop from the needle-opening over the upper side of the spool, While the spreader and hook together have carried the intermediate portion of the loop acrosslthe end of the spool through the opening b* of the spool-frame. The continued movement of the parts, as shown in Fig. 12, carries the lower portion of the loo between the adjacent arm c3 of the spoo driver and the end of the s o ol, and so comletes the encircling of the atter by the loop.

uring such action of the parts in passin the thread-loop around the end of the spoo the spool-frame and spool are being moved in opposition to each other, the timing of the parts being such that as soon as the loo is carried through the opening b4 of the spoo -frame the spool moves across such opening. hen the parts reach the position shown in Fig. 8, With the opening b* of the spool-frame at the o posite end of the spool, the loop has also een moved to such osition by the action of the loop-seizing hoo e moving in a direction contrary to the movement of the spool and is Jfree to be drawn up by the usual take-up to interlock With the under thread, as shown in Fi s. 8 and 13, and complete the stitch.

he particular form of the loop-seizing hook as described enables the same to enter vthe thread-loop as it is thrown out by the needle and continue its movement Without requiring additional slack thread until the blade e3 has fully entered the loop and the latter has passed around to the rear end of the blade, during which time the needle has moved above the Work bein operated upon, as shown in Fig. 10. The a vantage secured by such action of the parts is that the hole made in the goods by the passage of the needle therethrough is not obstructed by the presence of the needle when the thread is being drawn through said hole by the hook e, thus reducing the friction on the needlethread.

Any suitable means may be employed for acting in combination With the loo -seizin hook to engage with one side of the lJoop an carry the same across the end of the s ool and around its inclosing case, as described. The loop-spreader, as herein shown, consists of the thread-engaging iingerf, which is carried at one end oi' a lever f 2, the latter being pivotall f connected at its opposite end to a vertical y-disposed lever f3, which is fulcrumed on a lug f* on the under side of the bedlate and rovided with a in having an ant' riction-rol f5 thereon, Wlln'ch extends Within a cam-groove j", formed in a sleeve Which is secured on the shaft d. This cam f imparts a horizontally-reci rocating movement to the leverf. An elbow-leverfl, fulcrumed on a lug f8 on the under side of the bed-plate, is provided with a stud f on one arm, extending into a longitudinal slot f 0 in the lever f2 and with a connected antifriction-roll]m on the other arm extending into a cam-groove f 12, formed in a sleeve which is also secured on a rotating shaft d. This lever f 7 is operated to communicate a vertical movement to the lever f l and, acting in combination With the lever j 3, causes the threadengaging finger f of the lever f 2 to move in a substantially circular path around the spoolcase and inclosed spool, the position assumed by the parts at diilerent times in their operation being shown in Figs. 2 and 3.

As before described, the loop-seizing hook e moves in a path at one side of the path of the reciprocating spool and after the threadloop has been assed around one end of said spool carries t e loop to the opposite end of t e latter and in position to be drawn up by the take-up through the opening t* of the spool-frame. The thread-loop in being carried longitudinally over the spool-case is thus acted upon only at one side of the latter, and consequently would cause that portion at the opposite side of the spool-case to drag. To prevent such drag and insure the more positive and ra id action of the loop in being passed-longiturinally over the case h, I employ -a loop-pusher for engaging with the loop on that side of the case op osite the hook e and pushing the saine in a direction in opposition to the movement of the spool, whereby the loop Will be directly enga ed at opposite sides of the case and positive y carried from one end of the latter to the other. The looppusher, as more clearly shown in Figs. 2, 7, and 8, consists of a plate i, Whichis movably supported on the spool-frame With one edge thereof extending into a longitudinal open slot it in one side of the spool-case h and provided With a notch i in such edge, which permits of the passage of the loop-spreader therethrough in carrying the loop around the end of the spool and also forms a shoulder i2, Which is adapted to en age with the side of the encircling loop, as s iown in Fig. 12, and, moving in the same direction with the spoolframe and in opposition to the movement of the spool, push said loo to the opposite end of the spool-case and o i' the same, as shown in Fig. 8. The edge of the plate i extending into the slot k of the spool-case revente rocking movement of the latter Wit `its inclosed spool and also positively insures the IOO IIO

engagement of the thread-engaging shoulder 'i2 with the thread-loop which has been carried across the said slot, as shown. When the loop-pusher is movably supported on the spool-frame, it is connected with the latter to be o )erated thereby through the medium of toggle-links i3 i3, which are centrally supported and controlled by a connecting-link ifi, which is pivotally connected with a fixed sup ort t5 on the under side of the bed-plate. Sucli connection secures a differential movement of the loopusher relative to the spoolframe, whereby t 1e former is caused to move faster than the latter during such time as it is pushing the thread-loo i, so as to insure the latter being pushed off t c end of the spoolcase and drawn up through the opening b4 of the spool-frame before such opening is closed by being entered into the spool. The looppusher ma r, however, be formed as an integral part o the spool-frame, as shown in Fig. 16, or be otherwise constructed and supported to roperly perform its function, as described? without departure from my invention.

To provide for placing the spool in position upon the rods b2 of the spool-frame or removing it therefrom, one of said rods has a screwthreaded connection with the frame, as shown, whereby it may be moved to increase the space between the ends of the said rods sueiently to permit of the spool being readily slipped on or 0H the same. Such movable rod has a crank-handle bQ as a means for operating the same.

The wooden spool b3 is adapted to ride directly upon the rods b2 Without any intermediate support, as I find that the friction caused by lint, dust, or other foreign matter gettin between such parts has no appreciable e ect upon the action of the same, as it does in the case of a metallic su port for the spool riding upon said rods. 'Iihe spool, being supported in such manner, also permits the spool-case being made very chea simple, and light, the same being pre Verably ormed of a simple ieee of sheet metal bent into a substantial y cylindrical form, as shown. This case is ada ted to be supported upon the eripheries o? the end flanges on the spool and be retained in position against undue endwise movement thereon by means o' the arms c3 c4 of the spool-driver, engaging the opposite ends of the same. Rocking or turnin of the spool-case h, as before describe is prevented by means of the looppusher i extending into the open slot h', with.

Which said ease is provided. In lieu of such slot in the spool-case, however, the latter mi ht be rovided With a tongue h3 thereon an the e ge of the loop-pusher be provided with a groove h* to receive said tongue, as shown 1n Fig. 15. Such a construction would accom lish the same purpose as the construction' st described. The space between the opposite ends or arms c3 c4 of the spool-driver is of course greater than the length of the spool-case, so as to )crmit of the needle-thread loop being readily passed between such arms and the adjacent ends of the case when the latter', with its inclosed spool, is being passed through said threadloop. The rear arm e of the spool-driver eX- tends upward across the center of the spool b3 and is provided with an opening es therein, which receives the rods b2 of the spool-frame, and is also adapted to permit the thread-loop being drawn upward by the take-up without liability of getting caught between the end of one of the rods b2 and the said arm c4, as will be obvious upon reference to Fig. 8. The spool-case may be provided with any suitable means for giving the desired tension to the under thread, the same, as herein shown, being formed with a series of arms h5, over and under which the thread is passed, as shown in Fig. 14. The case z is also provided with a number of slots or openin s, as shown, adapted to lighten the same an also permit the operator to sec the inclosed spool Yor the purpose of ascertaining from time to time the amount of thread remaining on the spool.

In order to provide a simple and practical means 'whereby the different makes, kinds, sizes, and numbers of commercial spools of sewing-thread, which vary more or less in size, may be used in the machine by the ordinary operator, I provide a series of eases, each being provided with the proper indicative numbers or characters stamped or otherwise located thereon to denote the one or more kinds of thread which it may be adapted to contain. For instance, the ease illustrated in Figs. 4, 5, and 6 and marked A, B, D silk indicates that such case is adapted to inclose commercial spools of sewing-silk of the three numbers indicated. The several spool-cases are adapted to the particular sizes and numbers of the spools of thread which they are intended to inclose by having their inner diameter and length of the proper size to contain the particular spool wlthout undue movement of the latter therein. For instance, a case intended to inclose a No. cotton, as in Fig. 14, is reduced both in diameter and length to correspond to such size of spool, the length being regulated by providing the case with an inwardly-projecting shoulder k7, it bein understood that the length of the severa cases are uniform to properly fit between the engaging ends or arms of the spool-driver.

Having thus illustrated and described a lgraetical embodiment of my invention, it will e obvious that the same may be more or less materiell modified without departure from the spirit of the invention, also in lieu of the commercial spool for carrying the under thread as described an ordinary bobbin IOC Wound in the usual manner might be employed, and I Wish it to be understood that the term spool es used throughout the specification and claims unless otherwise defined is intended to cover a bobbin or any other similar thread-carrying device.

In a sewing-machine, the combination, With the needle and its operatin mechanism, of a spool carrying the under t read, a oase inclosing said spool, a reciprocally-movin frame supporting said spool and case an having an opening for the assage of the needle-thread loop, means or passing the needle-thread loo around one end of said spool-case, and a oop-pusher carried by said spoolframe for pushing the thread-loop a ong the spool-case.

23. Ina sewing-machine, the combination, with tbe needle and its operating mechanism, of a reciprocally-moving spool carrying the under thread, a ease inclosing said spool, means for passing the needle-thread loop around one end of said spool-case, a looppusher, consisting of a plate supported with one edge thereof loosely enga ing with the spool-case to hold the latter iyrom turning, and provided with a notch in that edge thereof adjacent to the s ool-case forming a thread-engaging shoul er, and means for 1m- 1parting a reciprocating movement to the oop-pusher in opposition to the movements of the spool.

24. In a sewing-machine, the combination, with the needle and its operatin mechanism, of a spool carrying the under t ead, a support for the spool, a case inclosin said spool provided with an open slot exten `ng lengthwise through the same, means located exteriorly of sald case and extending loosely into its slot so as to prevent a turning or rocking movement of the case with its inclosed spool, and means for passing a needle-thread loo around the s ool and spool-case to interloclE with the un er thread.

25. In a sewing-machine, the combination, with the needle and its operating mechanism, of a commercial spool carrying the under thread, a support for said spool, a cylindrical case supported directly upon the peripheryr of the end langes of the spool and having a stop projection located on its inner Wall at a point distant from the end of the case so as to engage with a spool of less length than the latter and prevent undue endwise movement of the same, and means for passing a needlethread loo around the spool and spool-case to intel-leali with the under thread.

26. In a sewing-machine, the combination, with a spool-sup ortin frame comprising two pins or rods, o a spoo carrying the under thread riding directlyT upon said pins, an openended cylindrical case supported upon the periphery oi' the end flanges of the spool and means independent of the case for holding the same in longitudinal position upon the spool and communicating a reci rocating movement to the case and its inc osed spool.
